Privacy screen seamlessly, conveniently, and easily attaches to and detaches from the MacBook Pro frame with magnets. No inconvenient and potentially damaging adhesives required. Even with the privacy screen attached, the MacBook Pro can close completely to enter sleep mode. Limited viewing angle narrows the field of vision to +/- 30 degrees, helping keep the information on your screen private and reducing the chances of a visual data breach in the office or in public. Blue light reduction filters out harmful rays by up to 52%, easing eye strain and reducing the chances of blue light interrupting natural sleep patterns. Low reflective coating reduces glare from outside light sources for improved viewing clarity. With reversible viewing options, one side has a matte finish to reduce glare and fingerprints. The other side is glossy and provides a clearer view of the monitor. Magnets make it easy to detach and reattach.
